Abstract

The cooling arrangement has a distributor (6) which is provided with vertical ducts (7). In the upper and in the lower part of the slot (2) upper (8) and lower (16) collecting ducts are arranged which are connected to one another and to the distributor ducts (7) with the aid of cooling ducts (12') of the winding (11). The arrangement ensures effective cooling and is comparatively simple in design.
